The Bundesliga is a professional association football league in Germany. At the top of Germany's football league system, it is the country's primary football competition. It is contested by 18 teams and operates on a system of promotion and relegation with the 2. Bundesliga. A total of 50 clubs have competed in the Bundesliga since its founding.

Since the 1970s, FC Bayern Munich has dominated the championship, winning the title 21 times. However, the Bundesliga has seen other champions with Hamburger SV, Borussia Dortmund, Werder Bremen, Borussia Mönchengladbach and VfB Stuttgart being the most prominent ones.

Germany was unusual, in that, unlike in most other countries, a unified national league structure was quite late in developing. The Bundesliga was not formed until 1963 and the structure and organization of the nation's football leagues have undergone frequent changes right up to the present day. The league was originally founded by the German Football Association, but is now operated by the Deutsche Fußball Liga.
